Insulin-dependent diabetes mellitus (IDDM) is a chronic disease that affects millions of people worldwide. While this term is commonly used to refer to the condition, there are other synonyms that can be used to describe IDDM. Type 1 diabetes, juvenile diabetes, and autoimmune diabetes are some examples of terms that can be used interchangeably with IDDM. These terms, which are more commonly used in medical practice, highlight the underlying factors of the disease. Type 1 diabetes, for instance, emphasizes the need for insulin injections to treat the disease, while autoimmune diabetes refers to the root cause of the disease. By using multiple synonyms, healthcare professionals can better communicate and treat patients with IDDM.
